Suck out dust with a household vacuum cleaner rather than bothering with compressed air. Most people have vacuums, and vacuuming is less likely to send dust where you might not want it.
Thanks for explaining yourself, thought you were being sarcastic.
When i browsed the issue a while back, i didn't see any mention of a vacuum, as i thought it would not suck powerful enough, especially trying to fit it to a very small hole, and getting strong suction.

As you can see from that thread, dude tried a vacuum, but still had issues....thats why i think compressed air will fully clear it out.
I'm gonna give the vacuum a shot, mine sucks really good.
And i don't think dust would affect the iPad in any way, since it does not carry a fan.....only clog up holes.
Off Topic: My PS3 fell victim to dust clogging up certain vents, and i guess overheated the board, and got a red light of death.
took it to a shop, and blowed it out afterwards......the dust that came out of that PS3 was overkill, WOW!!!....was not expecting that much.
